The period of Slavic liturgy came to an end with the death of Methodius and his disciples were forced to take refuge in the
court of the Bulgarian Tsar Simeon. A former monk who became an important military figure, Simeon was also a considerable scholar who commissioned the translation of many Byzantine texts into Slavonic.
The Tsar is shown in a magnificent Basilica, with the expelled priests being depicted in the upper mosaics. The Tsar is in every sense central to the composition, radiating
authority and grandeur; he is attended by philosophers, writers, linguists and scribes all intent on their work. The subject matter of their attention is the books and documents encapsulating the past and future of the
Slavic people
